Factors controlling oxygen isotope variations in firn were discussed. From the results of gross β-activity measurements, it is obvious that the cycle in oxygen isotope profile is once a year in some areas due to the seasonal variation in oxygen isotopic composition of snowfall. In other areas, the cycle is not once a year. The following two factors are considered to affect strongly oxygen isotope variations in firn, from the results of direct stake measurements of snow accumulation and observations of surface conditions of the ice sheet. 1) changes in time of erosion, deposition and none on snow surface, 2) subsequent movement of water vapor in firn.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00007924","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.32","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Water Research Institute, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Snow and Ice Studies, National Research Center for Disaster Prevention"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"名古屋大学水圏科学研究所"},{"subitem_text_value":"国立防災科学技術センター雪害実験研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1977-03-01"}],"displaytype":"detail","filename":"KJ00002477027.pdf","filesize":[{"value":"3.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002477027","url":"https://nipr.repo.nii.ac.jp/record/7924/files/KJ00002477027.pdf"},"version_id":"f2929923-a28c-423c-a0be-6e0f944e014c"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"南極みずほ高原からえた浅層ボーリングコアー中の酸素同位体の分布","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極みずほ高原からえた浅層ボーリングコアー中の酸素同位体の分布"},{"subitem_title":"Oxygen Isotope Profiles in Firn Cores from Mizuho Plateau, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["964"],"pubdate":{"attribute_name":"公開日","attribute_value":"1977-03-01"},"publish_date":"1977-03-01","publish_status":"0","recid":"7924","relation_version_is_last":true,"title":["南極みずほ高原からえた浅層ボーリングコアー中の酸素同位体の分布"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T11:50:39.604153+00:00"}
